The hammers can be fitted to mini-excavators, skid-steer loaders and backhoe loaders.Cat has produced 10 new E-Series hammers. They are available in both silenced and side-plate versions. Four of these hammers (the H35, H45, H55 and H65) have two mounting configurations for fitment to both Cat and competitor’s carriers.
The silenced hammers, identified with an “s” in the model designation, use a fully enclosed housing to suppress noise, which may be required in sensitive environments or on small carriers where the hammer is close to the operator. The suspension system on silenced models includes buffers at the top and bottom to absorb reflective forces and isolate them from the machine. A suspension jack helps to dampen vibration and sound. Non-silenced, side plate models are available for all four hammer sizes.
The hammers are designed to match the auxiliary flows and pressures of the Cat machine. The hydraulic ports are conveniently situated for quick coupling, and once the hammer is connected, it is ready to operate. To protect the hammer from internal stress, an automatic shut-off can be activated. This stops the piston when the hammer breaks through the material, which protects the hammer. The E-Series hammers have 47% fewer parts than the D-Series, resulting in easier maintenance. A single grease point is used for daily maintenance. Source: http://www.cat.com/
